Mars Attracts Steam — Price, Demo, Deck Status and PC Requirements

Price, Discount Window and Editions

The Steam price answer is short: Mars Attracts costs $18.74 in US dollars at the time of writing, which is 25 percent off a $24.99 list price. The discount is framed on the store page as an introductory offer that ends October 1, so the list price is the number to expect once the window closes. Only one purchase option exists for the base game, so there is no cheaper or more expensive edition of the game itself.

There is a bundle on top of it. The Supporter's Edition gathers the game with four extras and saves a further slice compared with buying them separately, which matters if you want the art and audio material rather than just the game.

Purchase option	US price at time of writing	Contents
Mars Attracts (base game)	$18.74, down from $24.99	The full 1.0 game
Mars Attracts Supporter's Edition	$27.78, down from $32.17	Base game plus Starter Pack, Artbook, Soundtrack and Making The Game Featurette
Separate DLC, all four	$20.96 total	Starter Pack $5.99, Artbook $4.99, Soundtrack $4.99, Making The Game Featurette $4.99

The contents of the bundle are worth spelling out, because the four add-ons are not gameplay expansions in the usual sense:

• Mars Attracts - Starter Pack, $5.99, the only one of the four that could plausibly affect a park rather than a shelf.
• Mars Attracts - Artbook, $4.99, the official art collection.
• Mars Attracts Soundtrack, $4.99, the official music release for the game.
• Mars Attracts - Making The Game Featurette, $4.99, a behind-the-scenes video.
• Buying all four separately costs $20.96, which is why the Supporter's Edition is the cheaper route if you want more than one of them.

Demo, Steam Deck Status and Live Player Numbers

Mars Attracts has a demo, and the store page treats it as a real product rather than a sample: the Demo Available badge sits in the purchase block with a Download Demo button, and Valve lists it as its own demo app with appid 3195160. What the official material does not say is whether demo progress carries into the full game, so treat that as unconfirmed.

Steam Deck status is the one place this page has to give an unsatisfying answer. The store page shows no compatibility badge at all for the game, and the structured app details contain no Deck compatibility field, which puts Mars Attracts in the unrated bucket rather than in Verified or Playable. If the Deck is your main platform, there is no official statement to plan around yet.

Store fact	Value at time of writing
Base price	$18.74 (25 percent off $24.99)
Discount window	Introductory offer, ends October 1
Demo	Yes, as a separate demo app (appid 3195160)
Steam Deck rating	None published
Features	Single-player, Steam Achievements, Steam Cloud, Family Sharing
Achievements	36
Curator reviews	42 curators
Review summary	Very Positive, 89 percent of 236 all-time reviews
Franchise listing	Top Indie Developers

For the query that sends most people here, the player-count number, the honest answer is that the number comes from Valve rather than from a tracker. Valve's own player-count service returned 47 concurrent players for appid 2760580 at the time of writing, and SteamDB-style sites simply republish that same official figure alongside historical charts. That is a point-in-time reading, so treat any single number as a snapshot rather than a trend.

PC Requirements, Languages and Achievements

The requirements block is unusually light, and that is itself the fact. The store page publishes a minimum of Windows 10 plus 3 GB of available storage, and nothing else: no recommended specification, no minimum CPU, GPU or memory values, and no macOS or Linux requirements because neither platform is supported. On a game that models hundreds of guests and their AI, the absence of a recommended spec is worth reading as an incomplete listing rather than as proof the game is light.

Language support is broader than the requirement block suggests. The store page lists eight languages, and every one of them has full audio, which is a stronger level of localisation than the interface-only support many indie builders ship with.

Area	Store-page detail
Minimum OS	Windows 10
Minimum storage	3 GB available space
Recommended spec	None published
macOS / Linux	Not supported
Languages	English, French, German, Portuguese (Brazil), Simplified Chinese, Spanish (Latin America), Spanish (Spain), Portuguese (Portugal)
Audio support	Full audio in all eight listed languages

Achievements are present and generous: the store page and app details both report 36 Steam Achievements, and Valve's global completion data shows a healthy spread rather than a pile of unearned entries. The earliest unlocks are map and progression goals, and the rarest are the 1.0 additions.

Before paying, four facts from this page are worth acting on:

• The demo is a separate app, so performance can be tested on your own machine without buying first.
• No Steam Deck badge exists, so do not buy expecting a Verified rating to appear later; the status is simply unrated.
• No recommended specification is published, which means there is no official target to compare a large park against.
• Full audio is supported in all eight listed languages, which is the detail to check if you play in something other than English.

Achievement tier	Example	Global completion
Early map progress	American Frontier	56.7 percent
Mid-game enclosure goals	American Frontier and Ancient Egypt stages	56.7 and 31.2 percent
Guest volume targets	250 guests in one park	9.0 percent
Financial goal	Pay off the starting loan	7.7 percent
Staff levelling	Hire a level 5 security guard	4.7 percent
Late 1.0 content	Casino and Prohibition map goals	0.4 and 0.3 percent
Completion	Finish the game	0.1 percent

The completion curve explains why the achievement totals look steep for a game with this many reviews. Finishing the game sits at 0.1 percent globally and a five-star park rating at 0.8 percent, so the long tail of these 36 achievements is genuinely long rather than merely grindy. The 1.0 additions appear as the newest and rarest entries in the list, which is consistent with the official announcement adding a casino map and an American Prohibition enclosure type with the launch build.
